Well if you have to add up to 180 degrees and you already have 90 degrees covered because of the right triangle then it should be 45 and 45
Answer:
LHS=(1-sin60)/cos60
=(1-√3÷2)/1÷2
=2(1-√3÷2)
=2-√3
RHS=(1-tan30)/(1+tan30)
={1-(1÷√3)}/{1+(1÷√3)}
={(√3-1)/√3}/{(√3+1)/√3}
=(√3-1)/(√3+1)
={(√3-1)(√3-1)}/{(√3+1)(√3-1)}
=(3-√3-√3+1)/(3-1)
=(4-2√3)/2
=2-√3

Step-by-step explanation:
The pages left = total pages - the pages read
(10b + 3) - (-2b +78)
10b + 2b + 3 - 78
12b - 75
The pages left is equal to 12b - 75
